DOOR FOR CREMATORIES.

Specification of Letters Patent.

Patented July 19141.

Application filed. December 18, 1913. Serial No. 807,516.

To Zt whom, it may concern Be it known that l, EDWARD M. JONES, a citizen of the United States, residing at Macon. in the county of Bibb and State of Georgia,` have invented a new and useful. Door tor Crematories, of which the following is a spe .-iticati m.

This invention relates to doors for crematories, lit being particularly designed for use in connection with a crematory of that type disclosed in a copending application tiled by me.

@ne of the objects of the invention is to provide a crematory door which will tightly seal the opening in the crematory so as thus to prevent interference With the drafts withing the crematory.

A further object is to provide a door having means whereby'currents oft cool air are permitted to circulate therein, thus preventing injury to the door such as might result from the intense heat to which 1t is subjected.

A further object is to provide a door of improved construction, the inner surface of which is made up of tire brick held to the frame of the door in a peculiar manner.

A 'further object .is to provide a door which is easy to niove and which is simple and durable in construction.

With the foregoing and view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter describedand claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, Without departing from the spirit ofthe inven-l tion.

1n the accompanying drawings the pre terre-d form of the invention vhas been shown.

ln said drawingsz-Figure 1 is a front elevation of the door portions of the adjacent structure being s own. Fig. 2 is a seck tion on line A-B Fig. 1. Fig. 3 is a plan view. Fig. 4- is a section on line C--D Fig. 2. Fig. 5 is a detail view of one of the wedge engaging brackets.

Referrine to the figures by characters of reference Fdesignates a portion of a crematory in which is formed adoor openm F. The wall of the creniatory is provided ong the top of the @poma wi h other objects in n `eulate through they spaces a ytace plete l 1 which extends throughout the vfidth of the opening F and is provided, at its center and adjacent each end, with a bracket formed wit-ha depending lip 3,the lips of all ot' the brackets converging in one direction toward the tace plate 1. The brackets are of different widths, as will be seen by referring to Fig. 3, the bracket at one end being wider than the middle bracket and the bracket at the other end being-narrower than the middle bracket.

A rail 4 extends across the door opening F at the bottom thereof and outside'ot the cermatory and serves to support and guide wheels 5 on which the door proper is mounted. As shown in the drawings the door consists of a frame 6 with side barsl having outturned inner flanges 7 and inturned outer flanges 8 while arranged along the inner sides ot' the side bars of the frame are beads 9. The outturned tianges 7 are adapted, when the door is in closed position, to press against the face plate 1 and additional face plates 10 secured along the sides of the opening F. The bottom bar ot' the frame is not formed with an outturned flange 7 but, instead, is adapted to rest lat upon a sill plate 11, as shown in Fig. 2. The intur'ned ianges 8 are secured to a plate 1Q forming the outer surface of the door and secured to the inner side of the plate are angle bars 13. These angle bars are vertical and spaced apart at regular intervals, there being a longitudinally extending head la formed along the inner end of each bar 13, these heads being disposed in the same plane with the beads 9. Thus it will be seen that fire bricks having longitudinal grooves 16 in their side edges, can be positioned between the sides of the frame 6 and the bars 13, the grooves or channels being occupied by the heads 14 and beads 9 so that the fire bricks will thus be held securely in lace. Furthermore air spaces 17 will thus e formed between the fire bricks and lplatey 12. Air inlet openings 18 are formed inthe plate 12 close to the lower bar of the frame 6 and air outlet openings 19 are formed in the top bar of the Jframe 6. Thus it will be seen that air is free to cir- 17, the cool air entering the openings 18 and leaving by way of the openings 19. Thus the plate 12 will be kept'coo'l at all times and warping of the door will be prevented.

Brackets 9.0 are secured to the plate. 12 and the wheels 5 are journaled between the lower ends oftliese brackets and the plate. An arm 2l extends upwardly from the plate l2 and carries a roller QQ adapted to travel along the face plate l. lVedging blocks 23 are carried by the upper bar of the frame G and are spaced apart distances equal to the distances between the brackets 2. These blocks are of dilerent sizes, the largest block being arranged adjacent one end of the frame G and the smallest one being located adjacent the other end of the frame. Thus it will be seen that when the door is moved to closed position, the two smaller blocks will travel between the larger bracket 2 and the face plate l and the smaller block will travel between the face plate l and the intermediate bracket 2. Finally, as the door comes to closed position, the three blocks will become wedged behind their respective brackets 2, thus cansino' thedoor to bind tightly .npon the face plates. During this binding operation the wheel Q2 will arrive opposite a small recess 24. formed in the face plate l so that a slight lateral shifting of the door toward the face plates is thus permitted. The outturne'd inner flange of the top bar 6 extends at all times back of the lip 3 so that the door is thus prevented from falling laterally away from the face plate 1 while being moved to or from open position.

' This will be apparent by referring to Fig. 2.

As shown in the drawings a stokin door Q4: and an ash door 25 may be provi ed in the structure of the main door.

Vhat is claimed is `1. The combination with a structure having a door opening, of brackets extendingoutwardly from the structure and above the opening, said brackets having depending lips, all of the lips converging in one direction toward the structure, said brackets being of different widths, a door movable into and out of position across the opening and having upstanding wedging blocks movable simultaneously into engageinentlwith the respective lips to bind the door against the structure.

2. The combination with atstructure having a door opening and a face plate secured along the `top 'of the opening and formed withv a recess. of brackets y"extending out-KK wardly from the face plate 'and having de'- pend-ing lips, all of said lips converging in one direction toward the face plate, said brackets being of different widths, a 'door movable into and out of position across the opening and including a frame having an upstanding ange, said flange being movable between ,the face'. plate and the lips, wedging blocks carried bythe frame and movable simultaneously into engagement with the respective lips to bind the frame against the face plate, there being a recess in the Jface plate, and a horizontally revoluble wheel connected to and extending over the door and movable into the recess during such binding action.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
